Here’s a nice park.io flip we noticed just in time for the Holidays: a park.io user bought the domain libr.io in August 2015 for just $99 (as they were the only person to order it). It just sold last week on Sedo for $4,999. Nice job!
These aren’t random one-off lucky sales. As Mark Levine posted on Twitter - he sold six .io domains he bought on park.io in 2016 for 12x-15x ROI.
